D-Day: As It Happens is a real time 24-hour history event. Broadcast across TV, online and social media, it tells the story of this pivotal event in a completely new way.

Viewers will track the real time progress of seven people who were there on the day - each a real participant in the 1944 invasion - through a series of moment-by-moment updates using archive film, photographs, radio reports, diaries, letters and official records. All the primary source material will be released at the very moment it depicts.

This innovative project draws on unpublished research by Colin Henderson, a British historian who has spent the last 15 years meticulously analysing the archive material on D-Day to identify individual soldiers.

Its the first history television programme to apply the information revolution of the present to the past, delivering a fresh sense of immediacy and revealing the raw, emotional experience of those who lived through it.
